ATTACHMENT FOR LOCDMOTIVES.

To all whom it may concern:

Be it known that l, GEORGE C. AOKaR, a citizen of the United States, and a resident of Jacksonville, in-the' county of Duval and- State of Florida, have invented certain new and useful Improvements in Attachments for Locomotives, of whichthe following is a specification.

My invention is an improvement in attachinents vfor locomotives, and has for its object to provide a new and improved shoe and wedge for locomotive driving boxes, wherein the shoe and wed e are steel, with an interchangeable cuff or acing of brass or bronze on the wearing surface to permit the replacement of the cuif or facing when worn, without requiring a new shoe or wedge.

In the drawings:

Figure 1 is a sectional view through a driving box provided with the improved Fig. 2 is a section on the line 2--2 of, Fig. 1, looking in the direction of the arrows adjacent to the line; I

Fig. 3 is a perspective view of the wedge;

Fig. 4 is a similar view of one of the ends or facings;

Fig. 5 is a vertical section through the device;

Fig. 6 is a similar view through the shoe.

In the resent embodiment of. the invention, the improvement is shown in connection with the driving box 1 of'a locomotive, the said box being mounted in the usual frame 2. The shoe 3 and the wedge 4 are arranged between the driving box and the sides of the o suing for the box in the usual manner, the e e being at one side and the wedge at the other, and it will be noticed that both wedge and shoe are channel shaped. the inner wall of the bottom of the wedge being inclined as shown.

'lhat wall of the opening in the frame for the driving box with which the wedge cotiperates is also inclined, as indicated at 6, and by means of a set screw 7 having lock nuts 8 the wedgemay be moved vertically to compensate for wear, being moved inwardly toward the driving box as it is moved upwardly.-

As is known, isfactory bearing in constructions of this character, but a large amount of brass is required for wedges and shoes of this character. With the present invention the body and larger portion of both. wedge and shoe Specification of Letters Patent.v

are of cast steel, which will last indefinitely, v

while the wearing surfaces only are of brass or bronze. v

As shown, both wedge and shoe, which are the same so far as the bearing surface or facing of bronze is concerned, are cut away on the outer faces of their bottom and side walls, as indicated at 9 and 10, respectively,

and the ends of the cutaway portion 10 on the side wall are rabbeted or cut away, as

indicated at 11.

The 0nd or facing of bronze or brass shown in Fig. 4 is also channel sha ed, con sisting of a bottom wall 12 and side walls 13, and the ends of the side walls are beveled as shown at 14:, to fit the undercut ends 11 of the rabbets on the side walls. The ends of the bottom wall are square, and it will be evident that the cuff or facings ma be slipped on from the bottom wall 0 the wedge or shoe.

At the center of each side wall on the rabbeted surface there is a substantially-triangular lug 15 having its base at the free edge of the side wall and having its a ex at about the center of the rabbeted portion, and the sidewalls of the facings or ends are notched, as indicated at 16, to fit these'lugs.

I claim: v 1. In a locomotive drivin box, the combination with the box, of a s cc and a wedge arranged at opposite sides thereof between the same andthe frame, both shoe and wedge being channel shaped and being cut away or rabbeted on the outer face intermediate the ends-to receive a lining or facing of alloy, said lining or facing and the wedge or shoe having means for holding the lining or facing in place. l i

2. A wedge or shoe for locomotive driving boxes having its outer face cut away or rabbeted intermediateits ends on the bottom and side faces, and a channel shaped cuff or facing seated in the rabbeted portions, the

ends of the rabbeted portions at the sides of y the shoe or wedge being undercut and the ends of the side wall of the facing being shaped to fit said undercut ends, the shoe or wedge having at each side wall intermediate the ends of the rabbeted portion lugs,- and the cud or facing being notched to receive the lugs.

3. A wedge '01 shoe for locomotive driving boxes having itsouter face cut away or rab-' beted intermediate its ends on the bottom and side faces, and a channel shaped cuff or facing seated in the rabbeted portions, the vhich the shoe seats, said shoe and cufi' havends of the rabbeted portions at the sides 1of 111g means for holding them together. the shoe or Wedge being undercut and tie ends of the side Wall of the facing being GEORGE COE K 5 shaped to fit said undercut ends.
